A tennis player puts a first serve in with probability 0.65 and then wins the point with probability 0.81. If the first serve is not in, the player puts a second serve in with probability 0.84 and then wins with probability 0.59. A point is lost if the second serve is not in.
Draw a probability tree for this model.
Find the probability that the player wins the point.
